SPECIFICATION forming partof Letters Patent No. 528,132, dated October 23, 1894.

Application tiled November 3,1893. Serial No. 489,951. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM J Ess, a citizen of the United States, residing at Delray, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in Fluo-Cleaners; and I do declare the following to beafull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a iiue cleaning device, for cleaning the smoke flues of boilers,

and consists in a certain construction and ar-- rangement of parts as hereinafter fully set forth, the essential features of which being pointed out particularly in the claims.

The object of the invention is to produce a flue-scraper of simple and strong construction, in which the arrangement is such that the scraping rib or iiange is made to conform to the interior of the i'lue, and to accommodate itself to the varying diameter thereof. This object is attained by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my improved device. Fig. 2 is an enlarged horizontal section through the same. Fig. 3 is an enlarged perspective in detail of one of the sections of the scraping rib.

Referring to the letters of reference, A designates the stem upon which the Scrapers are mounted, and which is provided with a threaded shank b upon which is screwed a collar B having an annular flange a, which forms a socket or cup in which is seated the coiled spring c surrounding said stem. C designates a sleeve adapted to slide over the ,flange a, of said collar, and having a closed outer end against which one end of said spring bears.

D designates a series of spring arms which is bowed longitudinally and upon which at their longitudinal center, the scraper heads E are secured. These heads are provided with a transverse segmental rib d, and with the oblique acuminated and slightly curved ribs e that are intercepted by said rib d, be-

ing located on opposite sides thereof and at an angle thereto, said ribs e standing in separate parallel planes and having a slight opening'fzl in their upper edges adjacent to the 'face of the ribs d, for the passage of the soot and some distance apart, there being a slight opening i in the upper edge of said ribs e adjacent to the face of the rib dfor the passage of the soot.

The arms D are arranged about the stem A, their rear ends being detachably secured in a revoluble ring f seated in the end of the sleeve C and the outer ends of said arms being secured in like manner in a ring g j ournaled in the cap F that fits over the outer end of said stern and is secured by the nut h. The arrangement of the partsis such, that, when the arms are so secured, the ends of the segmental ribs d will lap, as shown in Fig` 1, to permit of the free action of each of said spring arms, so that the circular rib formed by said segments d, may expand and contract diametrically to accommodate itself to the varying surfaces of the interior of the iiue, `whereby contact with the inner wall of the flue is always assured, and the scraping of its entire surface eected.

The elongation of the spring arms D is provided forin the"` sliding sleeve C, which is held forward against said arms by the tension of the spring c, but which will slide rearwardly upon the annular flange a, when the resistance of said spring is overcome, thus allowing said sleeve to vibrate, and keeping the Scrapers at all times in contact with the wall of the flue. The proper tension is applied to said spring by turning the threaded collar B, as will be Well understood.

H designates a threaded socket of the shank of the stem A, into which a rod I is screwed, of sufficient length to enable the passing of the scraper head through the iiue. When the scraper is entered in a Hue and reciprocated therein, the contact of the oblique ribs e, with the wall of the flue,=will cause aslight rotary motion of said scraper as rit is moved longitudinally through the iiue, whereby the soot is perfectly removed and entirely withdrawn from the flue by means of the segmental rib sections d. The opening at the ends of the oblique ribs c, prevents the accumulation of IOO soot in the angle between the ribs CZ, e, as the scraper rotates.

This improved scraper is simple and effective, and by its use the iiues may be quickly and perfectly cleaned, and as the scraping ribs are the only wearing parts, should they become broken or worn out, they may be readily replaced.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a flue scraper, the combination of the stem, the rotary rings mounted thereon, the curved spring arms secured at their ends in said rings,'the scrapers mounted on said arms saidscrapers consisting of the segmental ribsections and the oblique acuminated ribs that arev intercepted by said segmental ribs being located on opposite sides thereof and upon separate planes, one of said rings being mounted to slide on said stem to permit of the free movement of said arms.

2. In a device for the purpose set forth, the Y combination of the stem, the rings journaled thereon, the spring arms detachablyT secured at their ends in said rings, the scraper heads secured to said arms, said Scrapers consisting `of the segmental rib-sections and the oblique acuminated ribs that are located on opposite sides of said rib-sections in separate planes and-intercepted thereby, the sleeve mounted to slide upon said stems and bearing against one of said rings, the spring in said sleeve e WILLIAM J ESS.
